[Pharmacological and clinical aspects of S-adenosylmethionine (SAMe) in primary degenerative arthropathy (osteoarthrosis)].

After some preliminary remarks of a biochemical and pharmacological nature, the authors have started a clinical study to test the antiinflammatory activity of the S-adenosyl-methionine (SAMe). An open trial, carried out on 90 patients with severe degenerative arthropathies has shown that 30 mg SAMe intravenously twice a day for 14 days have a marked anti-inflammatory effect a rather term and no side-effects. In a "double-crossover" investigation, SAMe was next compared to indomethacin by i.m. administrations to 15 arthropathic patients. The therapeutic responses of the two drugs proved exactly alike, whereas the side-effects following indomethacin administration were not present after SAMe. In 9 patients affected with rheumatoid arthritis administrations of SAMe have proved less effective, although some clinical parameters showed improvements.

Human leukemic intermediate DNA components.

The DNA extracted from human leukemic leucocytes has been fractionated on a methylated albumin kieselguhr (MAK) column. The different fractions obtained have been reannealed to a Cot value of 20 mol times sec/1 to study the distribution of the intermediate DNA on the MAK column. Intermediate DNA contains two components, one (CsCl density after reannealing, 1.703 g/ml) obtained by reannealing high molecular weight DNA, the other (CsCl density after reannealing, 1.707 g/ml) obtained only by reannealing sonicated low molecular weight DNA. High molecular weight intermediate DNA (1.703 component) is eluted early from the MAK column in the fractions corresponding to the main DNA peak, while low molecular weight intermediate DNA (1.707 component) is more widespread on the MAK column, but appears to be enriched in the fractions eluted later. The possibility is discussed that the latter component is interspersed in that part of the genome which is apparently more homogeneous in density in an analytical CsCl gradient, and is absent on the skewed, more heterogeneous, heavy side of the main DNA in CsCl.

Hybridization of mouse leukemia virus c-DNA to mouse repeated DNA sequences.

Experiments of hybridization between mouse leukemia virus synthetic 3H-DNA probe and mouse main band and satellite DNAs indicate that there is not a higher concentration of viral sequences in the satellite DNA. On the contrary, viral sequences appear to be enriched in the fast renaturing intermediate main band DNA.
